Assuming a computer has a single processor and a single core with no support for parallel...
Assuming a computer has a single processor and a single core with no support for parallel execution, explain why running a multi-threaded program would show no performance improvement. Would inter-process communication be relevant in such a context?

Your customer has requested that you upgrade his computer with a newer triple-core CPU and asks what his options are. You research triple-core CPUs on the market and tell him he has his choice of the following processor types? A. AMD Athlon II triple-core processor B. AMD Opteron triple-core processor C. AMD Phenom triple-core processor D. AMD Sempron triple-core processor

4. A multi-programmed operating system running on a single CPU assigns time slices of CPU time to the virtual machines that run the individual programs. Each virtual machine is given access to the CPU for a certain time (the time slice), during which it will continue to execute its program. The next time slice then goes to another virtual machine, and so on. Assume that each time slice is one millisecond (1/1000 of a second) long and the computer on...

A certain program is executed on a multi-core system and consists of two parts: Part1 and Part2. Part1 is a single task that is purely sequential and can only be performed by a single processor core. Part2 consists of N independent tasks. Each task in Part2 takes half the time required for the single task in Part1 and must be performed by a single processor core. a) If the number of cores is 16 and N (the number of independent...

Is it possible for a system with a single CPU to support parallelism? a) Yes - there can be multiple PCBs even if only one is active at a time. b) Yes - one of the fundamental design goals of an operating-system is to support resource sharing. c) No - the operating system would not support multi-tasking. d) No - there can never be two programs running at the same time.

When a program is run on Computer X, 70% of the execution time is CPU time . A better Computer Y reduces the execution time by 25%. It is know that Computer Y has a clock rate of 2.4 GHz, and it takes Computer Y 20% more clock cycles to execute the program. In addition, Computer Y can only reduce CPU time. What is the clock rate in GHz of Computer X? The answer must have exactly one digit after...

Jobs arrive at a single-CPU computer facility with interarrival times the are IID exponential random variables with mean 1 minute. Each job specifies upon arrival the maximum amount of processing time it requires, and the maximum times for successive jobs are IID exponential random variable with mean 1.1 minutes. However, if m is the specified maximum processing time for a particular job, the actual processing time is distributed uniformly between 0.55m and 1.05m. The CPU will never process a job...
